The Girl From Everywhere

"Nix has spent her whole life sailing the seas with her father, who possesses the ability to transport his ship and crew to any time and place — as long as he has a map to use as a guide. They’re on the hunt for one special map that will bring them home to Honolulu in 1868, where Nix’s mother is about to die giving birth to her. But Nix is afraid that by helping her father save the woman he loves, she’ll erase her own existence. This debut catapults delightfully from one map to the next, offering a fresh and captivating approach to time travel."
